The pilot of a Transcontinental and Western Airline luxury liner, coming into Chicago from the south, called Meigs Field to announce his approach. Clouds veiled the city, but he wasn't worried. Chicago didn't have any of those hundred-story buildings like New York; it had something to do with the fact that the city was built on alluvial soil, no bedrock anywhere near, soit wasn't easy to put up skyscrapers. It made things a little easier for pilots of the big trimotors . . . except that this time, as he looked up, he suddenly saw a huge tower where none should have been. He turned desperately to miss it. When he looked back, it was gone, and all thirty-eight of the rich and adventurous passengers behind him, who chose to take the plane in seven hours instead of the train in fifteen, were cursing his name.
